As for CNC machining projects, if there is a slight deviation in quality or tolerance range, it may lead to the failure of the project. So how to ensure the high precision and quality of CNC machining? This article will show you from various aspects how we specifically guarantee the quality of CNC machining parts.
Step One: Equipment
Equipment is crucial to ensure the accuracy of parts. Different types of equipment can achieve on-demand tolerance requirements. At the same time, the age of the equipment will also affect the tolerance to a certain extent.
At Ruitai, we have purchased various types of CNC machining machines (3-axis, 4-axis, and 5-axis) to process different materials while ensuring unique tolerance requirements.
At the same time, the machines and tools needs to be repaired and updated regularly every year. The high degree of automation of the CNC machine also meant that the wing was running most of the day, and the machine was prone to lose alignment due to vibration. That’s why it is necessary to ensure the machining accuracy of CNC machines.
Record keeping for CNC machining is anan important foctor. The QC team can monitor whether the CNC machine is abnormal in time through the saved machine processing records.
Step Two: quality inspection after processing
In addition to the quality assurance of the processing machine and the processing process, the quality inspection after processing is the last link in the entire quality inspection process. As for whether the processed parts can meet the customer’s precision requirements, various data passed through various quality inspection tools are strong evidence.
At Ruitai, we have a complete quality inspection team, which will conduct multiple quality inspections on each part during and after the processing. The specific quality detection steps include the following steps.
1). Sample testing.
Part quality inspection after the first batch of processing is necessary. Failure to conduct timely quality inspections on the first batch of parts may lead to failure of subsequent projects.
2). Quality inspection before delivery
After CNC machining, the finished part may undergo further surface treatment, and this step may affect the tolerance of the part to a certain extent. Therefore, we usually conduct further quality inspections on the parts after post-processing to ensure that these parts have no defects in appearance or tolerance errors.
Step Three: ISO certification
CNC processing companies that have passed ISO certification generally have more complete business and processing processes. This not only reduces material waste, but also reduces rework rates. And this is an important certificate to prove the strength of the processing company.
